We were finally heading on our 3-day expedition in Corcovado National Park, and I felt the familiar knot of nervous excitement in the pit of my stomach, as we walked in pre-dawn darkness towards the main street of Drake Bay. Bolivar, our guide from the locally-based Surcos Tours for the next three days, was waiting for us at the tourist office.
We already met Bolivar at the pre-departure briefing the night before, and the very necessity of such a briefing made me realize that a visit to Corcovado is not exactly a walk in the park. We discussed the condition of the trails and the available, albeit very limited facilities at Sirena Ranger Station, calculated the necessary quantities of provisions we needed to take, and walked through the potential dangers that a visit to a remote wilderness entails.
When we arrived at the meeting point at the tourist office, we were greeted with the much-appreciated flavoursome Costa Rican coffee. As we sipped the hot brew, the sky slowly began to lighten and soon a pickup truck came rattling down the road to take us for a short drive to the boat landing.
What followed was a one of our wildest adventures in Costa Rica. That boat ride was as close to extreme sports category as I ever got.

When we finally reached the shore of Corcovado, the three of us, and no doubt most of the other passengers felt like battle survivors. But in the idyllic setting of Corcovado’s wilderness, the boat ride soon became a distant memory.
We waded out onto the beach and found a log to sit on while we waited for the boat to be unloaded. As I watched hundreds of Hermit crabs scatter away from underneath our log, I took a moment to appreciate the fact that we were finally in Corcovado.
Dubbed by the National Geographic as ‘the most biologically intense place on earth in terms of biodiversity’, Corcovado is the best place to see wildlife in Costa Rica.
Most importantly (for me), it is home to five species of wild cats: jaguars, pumas, ocelots, margays, and jaguarundi prowl these jungles at night. This place is probably, as close to a wildlife haven, as the modern-day planet Earth has to offer.
As if to prove my point, within 20 minutes of landing on the beach we were looking at the first endangered species of the trip. Two Endangered Baird’s tapirs were taking an afternoon nap in a shady puddle just off the trail that runs from the beach to Sirena Station.
We quietly made our way to the edge of their little swamp and sat there watching the odd-looking creatures sleep. It may not sound like much fun, but it felt incredible to be this close to the wild animals, to be so accepted into their world, especially considering that Baird’s tapirs are some of the most threatened species of wildlife in Costa Rica.
Sirena Ranger station
We entered Sirena station via the jungle airfield where a cute little 4 seater plane sat parked in the freshly mowed grass.
The Station had an idyllic appearance of a tropical research station that brought to mind images from the Jurassic Park movies, which came as no surprise since some of the films were actually filmed in Costa Rica. But behind the romantic façade, hid Sirena’s ugly truth.
The facilities were not simply dilapidated but seemed to be intentionally offensive. The only saving grace was the dining area and the wide wrap-around veranda of the ranger’s office. I could easily imagine lazing around after dark in the comfortable chairs on the veranda, watching wildlife emerge from the jungle.
But for now, we were content to have a quick cup of coffee and to leave the station to explore one of the trails.
Walking the trails in Corcovado
As soon as we stepped from the brightly-lit clearing of the station into the dim unknown of the jungle, we were engulfed into a different world that was absolutely teeming with wildlife. A beautifully-patterned Tiger snake slithered across our path. Exotic birds painted in vivid colors darted through the trees. Collared peccaries and White-nosed coatis scurried in the leaf litter completely unafraid.
Up in the trees, Howler monkeys and Squirrel monkeys raced across the canopy, dislodging ripe fruit that would land with a thud at our feet. It seemed like at every turn there was something amazing to look at.
Bolivar spotted a Northern Tamandua – Costa Rica’s largest anteater, high up in the canopy. It seemed to have too ungainly a shape for a tree-dweller, yet it moved with unexpected grace. It poked its curious face through the branches to have a better look at us.
Not to be outdone by the high flyers, a little Eyelash viper curled up on a branch by the side of the trail, perfectly camouflaged against the moss-covered bark. Apparently, ‘she’ can be found there any day, frozen motionless for hours, waiting for unwary prey to approach within her striking distance.
Our second day in Corcovado National Park started with a 4.30 am hike to the Sirena River in hopes of seeing tapirs taking a dip in the ocean. The tapirs appeared to have had an earlier swim that day, but watching the sun rise over Costa Rica’s Jurassic jungle was quite awe-inspiring.
Hike to Puma Valley
After an enormous and delicious breakfast back at the station, we set off to Puma Valley. I was desperately hoping to see a wild cat in Costa Rica and Corcovado National Park was my best chance.
I read reports of ocelot sightings, one even on the airstrip at Sirena in broad daylight, but Bolivar quickly and firmly liberated me from my delusions and assured us that the chances of seeing an Ocelot were next to none.
He did see Pumas in Corcovado however, twice, in his however-many years as a guide in the park. The aptly named Puma Valley was the place where his sightings occurred.
The valley lies along the main 16km La Leona track and to get to the start of the trail we had to cross a tidal creek. As we were wading through about a meter of water Ruth pointed at an impressively-sized crocodile floating just below the surface a few meters away.
Bolivar’s “Don’t worry they don’t eat people” dismissal of the croc, did not inspire too much confidence. I guess, after living in Australia for a few years you develop a healthy skepticism towards crocodiles’ dietary preferences.
Wild pumas in Corcovado
The trail to Puma Valley is a spectacular hike. It is flanked by dense tropical jungle on one side and by deserted beaches and the Pacific Ocean on the other. If I was a wild cat, I would’ve been very happy to live here.
As soon as we walked into the valley itself, Bolivar grabbed my arm and none too gently pulled me down into a crouch, pointing into the jungle. I looked in the direction he was pointing and met an intent stare of a puma.
It was no further than 4 or 5 meters in front of us. Unable to speak or even breathe from excitement, the four of us froze where we were, too afraid that the cat would dash away.
It didn’t. And after a while, another little face poked through the undergrowth – a cub!
Slowly, they started walking away. Bolivar whispered for us to stay put. There was a swamp behind the pumas and the only way for them to continue on their journey was to walk around it, right across our field of view.
He was right. And as the cats emerged from the undergrowth we noticed the second cub. The trio slowly walked around the swamp and disappeared into the thick undergrowth leaving us speachless for a few minutes.
I have chased enough cats in the wild to appreciate just how rare a sighting this was. When we returned to Sirena and Bolivar shared the news with the station rangers, they wouldn’t believe him until he the presented photographic evidence.
Later in the afternoon a group of 3 antipoaching patrol rangers walked into Sirena, rifles slung over their shoulders. These men spend 3 weeks in the field, in parts of the park that can only be accessed on foot. They sleep under the starts and see more wildlife than anyone else in Corcovado.
Bolivar had to present our photographs to these rangers as well, in order for them to believe him. I asked him to find out what cat species these rangers encounter during their time in the junge and he came back with two reports of Ocelot sightings (over a few years) and of a couple of puma sightings. Cats seem to be as elusive in Corcovado as they are in most places where they occur.
More Corcovado wildlife
The rest of our stay in Corcovado paled in comparison to seeing pumas but was still quite incredible.
The following day we returned to Puma Valley but didn’t see the cats, of course. But we did find some Baird’s tapirs snoozing in a shady puddle and at one point, a huge group of White-nosed coatis surrounded us on the trail. They completely ignored us as they dug around in the leaf litter looking for buried fungi virtually next to our feet.
Before we left the valley we picked up another couple of mammals: a Red Brocket deer and a Red-tailed squirrel, as well as a very impressive Pale-billed woodpecker.
Apart from the cats, another animal I wanted to see was a Tent-making bat. This curious bat builds its own home by biting the central vein of a large banana leaf until it folds in half, forming a V-shaped shelter that protects the bat from the sun and the rain. Bolivar found one near the creek, roosting underneath a large Heliconia leaf.
Back at the field center, a troop of Spider monkeys and Squirrel monkeys spent the afternoon squabbling in the low branches, birds of prey actively hunted large insects and Collared peccaries browsed on the grassy lawns. It was like living inside the Costa Rican edition of the Jungle Book.
South America’s most venomous snake
The one thing we kept missing in Costa Rica was Central America’s most infamous venomous snake – Fer de Lance. This snake is responsible for most snakebite-related deaths in the region. So when the chance to see one presented itself, we jumped to it.
It was the morning of our departure and we were lazing around at the station drinking some much-missed coffee. Suddenly, Bolivar came up brimming with excitement and a sense of urgency. One of the other guides told him that his group just spotted a Fer de Lance about a kilometre up one of the trails. And he offered to take us to the spot.
In a flurry of excitement, our coffee was completely forgotten and we took off at a trot after the guide. The trail was so muddy that the flip-flops we happened to be wearing were more of a hindrance than anything else, so we ended up carrying them in our hands instead.
This is what wildlife watching holidays are all about for me – running barefoot along a muddy jungle trail to see a venomous snake!
The viper, one of the most dangerous animals in Costa Rica, was curled up on the jungle floor barely distinguishable from the leaf litter. It would take real skill to spot it before stepping on it.
No wonder the guide volunteered to take us, rather than explain to us where the snake was. He obviously didn’t want to contribute to the count of unaccompanied foreign tourists that perished at Corcovado.
Here is our species list for Corcovado National Park.
To finish our adventure we were treated to a monsoonal downpour on the boat ride back to Drake Bay. Two hours under torrential rain, all the while thinking that we had our rain jackets packed too deep in our bags, which were stashed out of reach in the stern section of the boat.
How to visit Corcovado National Park
Ethical tour guide
It is compulsory to have a nature guide with you for visiting the remote wilderness of Corcovado. The access point for Corcovado is the small laid-back town of Drake Bay. We visited the National Park with Surcos Tours for 3 days and 3 nights.
Bolivar was a fantastic guide and without his help, we would not have spotted half of the animals we’ve seen. And while the wildlife is very approachable, you could even say tame, in Corcovado, we never approached the animals too closely. Unless they came to us themselves. We also made sure to leave no traces of our visit to the park’s trails and took all our rubbish back with us.
Be prepared to rough it a little — the accommodation in the park is very basic.
How to get to Corcovado National Park
The best part of Corcovado National Park that is open to visitors is Sirena Rangers Station. There are two ways to get to Sirena: by a day-long hike from Puerto Jiminez, or by a two-hour boat ride from Drake Bay. Carrying our backpacks for 8 hours in the humid heat of the tropics sounded like a tough gig, so we opted for the boat ride option.
